BRACELET CHAIN Application filed June 14,

vide a bracelet structure which will with stand longitudinal strainswithout separation.

Another object is to provide a sheet metal construction for ahraceletwhich will present an attractive appearance when worn. 1

l/Vith these and other objects in view, the invention consists ofcertain novel features of construction, which will be more fullydescribed in the detailed description following, and will be moreparticularly pointed out in the appended clan In the accompanyingdrawings:

Figure 1 is a top plan view on an enlarged scale of a chain formeo inaccordance with this invention;

Figure 2 is a plan view of a connecting link; A

Figure 3 is perspective view of a connecting link, with the edges turnedupwardly to form flanges, as in the finished chain;

Figure 4 is a sectional view on the line H of Figure 1, tioning of theflanged link edges and the chain body members, and

Figure 5 is a sectional view on the line 55 of Figure 1, showing therelative heights of the body members and the link flanges.

It is found desirable, in the formation of thin bands or straps forsecuring a Watch on a wrist, to produce the appearanceof a hollow linkconstruction and thus give the band a neat appearance while Worn, and atthe same time to reduce the manufacturing cost by simplifying themanufacturing proce- I therefore connect together frame showing therelative posi-' 1929.

and turn the edges of'the frame links up wardly to close the upperportion of the body link ends and to form an attractive border for thebody links without detracting from the flexibility of the band or strap;this construction provides a thin band or strap which will withstand thelongitudinal strain'to which it is subjected without separation of theconsituen't parts thereof; and the following is a detailed descriptionof the present embodiment of this invention illustrating thepreadvantageferred structure by which these ous results may beaccomplished.

Referring" to the drawings, 10 designates the frame link, generallyrectangular in shape and provided with a longitudinal rectangularopening 11 leaving end sections 12, 13 which, as shown, are preferablyarcuate in form. A sheet metal connecting link 14.

has wing portions 15, 16 which are folded around the sides of the framelinks, as shown in Fig. 1, to form substantially rectangular links. Theends 12, 13 of the connecting link are turned upwardly, as shown inFigure 5, to form an attractive border, or margin, for the body links,completely closing the greater portion of the open ends of the bodylinks so as to present an attractive appearance, and wrist.

Each of the parts of this strap is of thin sheet stock, the thickness ofthe strap being twice the thickness of the .body link stock plus thethickness of the frame link stock. The strap is flexible, is strong, andis eX- tremely thin.

The foregoing description is directed sole- 1y towards the constructionillustrated, but I desire it to be understood that I reserve theprivilege of resorting to all variations and mechanical changes withinthe scope of the invention, as defined bythe appended claim.

I claim: v

A bracelet chain comprising a series of also to prevent cutting the V jr 1,760,662

generally rectangular-shaped frame links, each having a longitudinalslot therein, and sheet metal links, each comprising a body portion withoppositely extending Wings, each extending through the slot of a framelink seated directly in contact With the body portion and foldedtogether With their edges 7 abutting, and end sections on said framelinks folded towards said body portions to form margins for said sheetmetal links.

In testimony whereof I affix my signature,

EUGEN PRESTINARI.
